Current data indicate that the reliability of contrast-enhanced sonography is still limited for liver tumors smaller than 2.5 cm diameter and lesions smaller than 1 cm can not be reliably characterized with this method [40]. In comparison with CT and especially with liver-specific MRI the value of contrast-enhanced sonography in daily practice is at present not firmly established, especially with regard to very small lesions. Moreover, the technique is still not as widely accessible as gray-scale B-mode ultrasound, since the technical equipment to perform contrast-enhanced ultrasound is not broadly available and a specific training of the examiner is necessary. Therefore, at present this method is rather a valuable add-on to CT and MRI than a substitute for either CT or MRI on a regular basis. [Pg.17]

Fig. 19.9. a Sonography of the jejunal GIST. An oval-shaped tumor with a deep ulcer is demonstrated. The tumor is well demarcated and the contour of the tumor is smooth, b Color Doppler ultrasound of the tumor shows the rich vascularity, c Contrast-enhanced ultrasound reveals the rich perfusion with a focal perfusion defect inside the tumor (asterisk), d Endoscopic feature of the tumor. A submucosal tumor with a deep ulcer at the center is demonstrated... [Pg.164]

Increasingly sophisticated, broadband or multiple focusing transducers also play an important role. Contrast-enhanced sonography can be performed not only with 3.5-MHz transducers usually used in abdominal ultrasound, but also with 5- to 12-MHz transducers which offer a higher spatial resolution. [Pg.174]

Incesu et al. (2004) demonstrated that power Doppler sonography has a sensitivity of 74% and contrast-enhanced power Doppler US a sensitivity of 100%, respectively, in the diagnosis of acute appendicitis (Table 20.5). In their study, feeding vessels of all inflamed appendices were visible. They concluded... [Pg.176]
